iphone - UIView上的两个UITapGestureRecognizer

Question

我想添加到我的UIViewController：

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture:)];
tapGesture.numberOfTapsRequired = 2;
[self.view addGestureRecognizer:tapGesture];
[tapGesture release];

UITapGestureRecognizer *tapGesture2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture2:)];
tapGesture2.numberOfTapsRequired = 1;
[self.view addGestureRecognizer:tapGesture2];
[tapGesture2 release];

问题是如果用户点击两次调用这两种方法，我希望如果用户双击只有第一个（handleTapGesture）会被调用，如果他点击一次它只会调用第二个（handleTapGesture2）

Answer 1

用这个..

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture)];
tapGesture.numberOfTapsRequired = 2;
[self.view addGestureRecognizer:tapGesture];
[tapGesture release];

UITapGestureRecognizer *tapGesture2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture2)];
tapGesture2.numberOfTapsRequired = 1;

[tapGesture2 requireGestureRecognizerToFail: tapGesture];

[self.view addGestureRecognizer:tapGesture2];
[tapGesture2 release];

Answer 2

您可以使用我在此处requireGestureRecognizerToFail:发布的代码在此使用 的方法viewcontroller.m将解决您的问题
